customizing themes

Ok, this is my first post. I recently purchased envato theme, however. I love that these themes come with generic content to make the process much faster and easier, but. Is there a plugin that can make the customization user friendly. I need a plugin that allows me to make changes but visually see the changes too, don’t know the correct term.
Please help.



if your purchased theme not included WPBakery Page Builder plugin. Then if your theme compatible with WPBakery Page Builder then you can purchased this plugin from here and can install.
